PITTSBURGH (KDKA/AP) – Pittsburgh and Allegheny County officials are mulling several policies – including limiting tailgating hours in stadium parking lots – to avoid messes like the one left behind by 50,000 Luke Bryan fans last month.

That June 21 concert, and another last year – also at Heinz Field – featuring Kenny Chesney, prompted a discussion involving government and parking officials, and representatives of the city’s three major sports teams on Tuesday at Mayor Bill Peduto’s office.

While the specific policies have yet to be determined, one idea that came out of the meeting is limiting tailgating to five hours before an event. Lots opened for tailgating at 10 a.m. for the Luke Bryan show, which began at 6 p.m.

According to a statement from Peduto last month, Pittsburgh Public Safety officials responded to over 300 Luke Bryan concert-related incidents.

“Pittsburgh Police issued 37 non-traffic citations (20 for scalping; 10 for public urination; six for disorderly conduct; and one for public intoxication); made at least seven arrests; broke up 15 fights and answered 154 calls to 911. City medics responded to 100 calls to 311 and made 34 transports to hospitals,” the statement said.

ALCO Parking took care of the parking inside of their lots. However, the city picked up the tab for cleaning the streets and the waterfront.

Moving forward, Peduto would like to see the promotors pick up part, if not all, of the clean-up costs.

Officials hope to have new rules in place before a Jason Aldean concert July 26 at PNC Park.
